To all whom it may concern: I

- Be it known that I, CHARLES I-I..AYARs, a citizen of the United.States, residing at Salem, in the county of Salem and State of .NewJersey, have invented certain new and useful Improvements in Can-FillingMachines, of which the following is a specification.

My invention relates to can filling machines and more particularly tomeans for agitating the materials and compressing them into the cans.Mechanism which is designed for use in canning granular materials maynot function equally well with comparatively bulky material such astomatoes or comparatively soft. materialsuch as string beans. p

The objects of my invention are to provide improved means for agitatingcomparatively bulky or-soft materials and compressing vthem into, the.vmeasurlng devices, and to provide such means which are readily adaptablefor use with granular materials.

These objects, and other advantageous endswhich will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which I Figure 1 is a plan view of acanning machine embodying my invention,

Figure 2 a vertical section through the hopper and turret, v

Figure 8 a plan view of the hopper plate,

Figure 4 an enlarged fragmentary section on line 4-4 of Figure 1 showingthe hopper and hopper plate at one limit of its oscillatory movement,

Figure 5 a like view showing the hopper and hopper plate at the limit ofits swing in the opposite direction,

Figure 6 a reversed plan view of a part of the hopper plate, I

Figure 7 a section on line 77 of Flgure 1, showing the hopper plate andshaker mechanism, the other parts being omitted, and

Figure 8 an end view of the shaker mechanism.

Referring to the drawin s, 1 indicates the hopper and 2 thehopper p atewhich is provided with an upwardly extending flange 3 to the upper partof which the hopper is secured. The part of the flange below the hopperhas a shouldered enlargement 4 in which is secured a compression member5 of ber.

;structure 14 at its outer end, the top rubber or other'elasticmaterial. The inner wall of the compresslon member 18 curvedat its upperand lower edges and slopes outlower curved edge. The hopper platepreferably has a curved upwardly extending groove 6, having a;perforated top, extending from flange 3 to a point over the dischargewardly from the upper curved edge to the port 7 of the turret 8, andcommunicating I with the space within the compression mem- 3 This grooveserves to convey granular material, which might otherwise be crushed,

to the discharge openingand also serves as an air vent. canning bulky orsoft material-the inner end of the groove may be closed by a detachableplate 9.

Axial oscillation of the hopper is effective I When the'machine is inuse for with granular material but not so effective that a swingingoscillation is equally or more with more bulky material and I have foundefiec'tive with both classes of material. I

therefore provide means for imparting a swinging oscillation'to thehopper plate and 1 hopper. For this purpose I position one end of thehopper plate'upo'n aboss 10 extending from'the frame and yieldingly con-'nect ittherewith by a pivot pin 11 and a spring 12." The oppositeend'of the hopper plate carries a bracket 13 having-abox like which isprovided with a longitudinal slot p 14 and the bottom with a like slotindicated at 15. The interior of the box houses "a block 16 which isslidable therein, and the box rests upon a wheel 17 adaptedto berotatedby any suitable mechanism. Wheel 17 carries an upwardly extendingeccentric pin 18 which takesthrough slot 15, block 16 and slot 14 and isyieldingly held to the box by a spring 19; Rotation of wheel 17 causesthe hopper plate to oscillate with pivot pin. 1

11 as the axis of oscillation.

I have illustrated the measuring wheel as ,j I

consisting of telescoping sections 20 and 21,

section 20 being supported by a bed plate 22, andthe two sections beingadapted to be rotated by means of a shaft 23 carrying a dog 24 disposedin an oblong opening 25in embraced by an inwardly threaded band28 byrotation of which the telescopingsections may be adjusted to vary thecapacity of the measuring receptacles.

The operation will be best understood by reference to Figures 4 and 5 ofthe drawings, it being understood that the hopper is filled and theshaker mechanism inlop+ eration and the hopper and compression memberthereby caused to swing to and fro 7 over the measuring receptacle whichis be ing charged. Figure 4 shows the measuring receptacle partly filledand the hopper at the limit of its throw to the left and Figure 5 showsit at the limit of its throw to the right. As it moves from left toright the part 'of the sloping compression member at the left exerts aw'edging pressure tending to press the fruit inwardly and downwardlyinto the measuring receptacle as shown in Figure 4. As the hopper isswung from right to left the part of the sloping compression memberat'the right tends to press the fruits inward and downward and thefruits are gently and snugly packed into the measuring receptacle. v

While I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence :I do notlimitmyself to'theprecise construction set forth, but consider that I amat libertyto make such changes and alterations as fairly come within thescope of the appended claims.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is 1. In acan filling machine, the combination with traveling measuringreceptacles of a plate carrying a hopper and having a pivot, ad1acentone edge, connecting it wlth the frame, and means for swinging the plateto and fro, with the discharge opening of the hopper over the measuringreceptacles, with said pivot as an. axis.

2. In a can filling machine, a plate carryin a hopper and a yieldingjcompression mem ber disposed under the throat ofthe hopper. Y

3. In a can filling machine, a plate. carrying a hopper and a yieldingcompression member disposed under the throatofthe.

hopper,.the compression member having its interior wall slopingdownwardly and out wfardly. I

4:. In a can filling machine, a plate carrying a hopper and a yieldingcompression member disposed .under the throat of the hopper, thecompression member having its interior edges curved and its interiorwallsloping downwardly and outwardly.

5. In a can filling machine, the combination of traveling measuringreceptacles, a plate carrying a hopper and mounted to swing to and frowith the discharge opens ing of the hopper over the measuringreceptacles, and a yielding compression member disposed under the throatof the hopper.

6. In a can filling machine, the combination with traveling measuringreceptacles of a plate carrying a hopper and having a pivot, adjacentone edge, connecting it with the frame,'a yielding compression memberdisposed under the throat of the. hopper, and
